Before the days of classless this made sense for people such as IBM, AT&T, GE, and the few others that have A's. It could be efficient for them to be apportion B's and C's from that lot for their global reach. I don't know how efficient that would be - and they could probably use supernetted B's. There are class B's out there too with under 1% usage. One I'm famiar with could easily spin-off 254 of their C's with no impact on their operation.
